The latest entry in Naughty Dog’s dev diary series, called “In the End,” takes an emotional turn as the developer grapples with saying goodbye to their beloved protagonist Nathan Drake in the upcoming Uncharted 4: A Thief’s End.

The developers spend time in the video thanking the fans for their commitment to the series and reflecting on what the characters have meant to them while working on the series for the past decade. Uncharted 4 has been confirmed to be the last title in the series, or at least the last one with Nathan Drake or Naughty Dog attached to the game, which has led many fans to wonder what will happen to their favorite thief once Uncharted 4 is all said and done.

Uncharted 4: A Thief’s End launches on May 10th for the PlayStation 4.
